Title: Positioning and actuating drive

Abstract: An electric motor, gearbox, position phase angle sensor and motor phase angle sensor are integrated in a common housing to reduce the size of a positioning and actuating system. The housing also includes electronics for detecting and processing the signals from the phase angle sensors. The rotor shaft of the electric motor is designed to be hollow, and the drive shaft is mounted coaxially. The output shaft passing coaxially through the gearbox, and the end of the shaft which protrudes from the gear box is provided with a coupling. The drive shaft passes coaxially through the rotor of the electric motor and carries a position phase angle sensor at the end of the electric motor opposite the gear box. The motor phase angle sensor on the rotor shaft coaxially encloses the position phase angle sensor. The scanning detectors of both sensors are arranged on a common circuit board, which also carries the electronics for detecting and processing the signals of these sensors. Thus the phase angle sensors and electronics can be compactly mounted in the housing. A second circuit board, carrying the control and power electronics can be integrated parallel to the circuit board carrying the sensors. Both circuit boards are arranged perpendicular to the axis of the rotor and output shafts, the circuit boards add little to the overall dimensions of the housing.
